SPECIFICATION forming part of Letters Patent No. 313,573, dated March10, 1885.

' Application filed November 9, 1882. Renewed January 13, 1885. (Model.)

To aIZZ whom it may concern:

Be it known that I, ELLIS S. BLOOMFIELD, J r., a citizen of the UnitedStates, residing at Jersey City, in the county of Hudson and State ofNew Jersey, have invented a new and useful Method of Striking Gongs, ofwhich the following is a specification.

My invention relates to an improvement for striking gongs; and theobject of my improvement is, first, to give a sharp, quick stroke, and,second, to get more weight to carry the striking-pin back to itsoriginal position. I attain this object by the use of a lever betweenthe striking-pin and the striker, which is so pivoted that a very slightmovement of the short arm causes the longer arm supporting the strikerto travel very rapidly, and as it moves toward the pivoted end of saidstriker lifts it with constantly-increasing speed against thegong,insuring a loud,clear ring. The combined weight of the striker andlever on their return insures a quick motion and return of thestriking-pin to its original position.

The mechanism is illustrated in the accompanying drawings,in whichFigure 1 is a vertical central section of a stand supporting a gong andthe striking mechanism. Fig. 2 is a front View of the same, showing thestriker resting in the lever and adding its weight to support thestriking-pin above.

Similar letters refer to similar parts in both views.

A is the stand, B the gong, and O the striker pivoted to the stand at a,and moving freely through the stirrup or lever D. E is thestriking-pin,passing down through the top and resting on the stirrup orlever at b, so that in pressing down upon it the lever is made to movein the direction of the arrow, lifting the striker against the gong inthe direction d c.

The dotted lines, Fig. 1, represent the position of the lever andstriker at the momentthat said striker reaches the gong. The lever D isstopped on coming in contact with the stand or some suitable projection,while the 4 momentum. given to the striker carries it I ELLIS S.BLOOMFIELD, JR.
